The combination of dorzolamide and timolol is used to treat eye conditions, including glaucoma and ocular hypertension, in which increased pressure can lead to a gradual loss of vision. Dorzolamide and timolol is used for patients whose eye condition has not responded to another medication. Dorzolamide is in a class of medications called topical carbonic anhydrase inhibitors. Timolol is in a class of medications called topical beta blockers. Dorzolamide and timolol lowers pressure in the eye by decreasing the production of natural fluids in the eye.
The combination of dorzolamide and timolol comes as a solution (liquid) to instill in the eye. It is usually instilled in the affected eye(s) twice a day. To help you remember to use dorzolamide and timolol, use it at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use dorzolamide and timolol exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
Dorzolamide and timolol combination controls glaucoma and ocular hypertension but does not cure them. Continue to use dorzolamide and timolol even if you feel well. Do not stop using dorzolamide and timolol without talking to your doctor.

Check the dropper tip to make sure that it is not chipped or cracked.
Avoid touching the dropper tip against your eye or anything else; eye drops and droppers must be kept clean.

Hold the dropper (tip down) with the other hand, as close to the eye as possible without touching it.
Brace the remaining fingers of that hand against your face.
While looking up, gently squeeze the dropper so that a single drop falls into the pocket made by the lower eyelid. Remove your index finger from the lower eyelid.
Close your eye for 2 to 3 minutes and tip your head down as though looking at the floor. Try not to blink or squeeze your eyelids.
